Permissible operating pressure in bar Kv values: MG 20 DN 15 DN 20 DN 25 6 m³/h 10 m³/h 12 m³/h Kv values determined acc. to DIN EN 60534, PP valve body with union ends and DIN insert. The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ. In general, all diaphragms are subject to the influences of pressure, temperature, the process and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the standard. 5 / 15

Add-on components Add-on components GEMÜ 1215 Electrical position indicator The GEMÜ 1215 electrical position indicator indicates one position of the valve. It is designed so that it can be mounted to GEMÜ valves via a female thread in the actuator housing. GEMÜ 1230 Electrical position indicator The GEMÜ 1230 electrical position indicator is suitable for linear actuators with up to 20 mm actuating travel. The device has either one or two microswitches. They are individually continuously adjustable via a threaded spindle. An LED display can be integrated as an option. GEMÜ 1235 Electrical position indicator The GEMÜ 1235 electrical position indicator is suitable for mounting to pneumatically operated linear actuators. Secure connection to valve spindle means reliable feedback signal. Intelligent microprocessor controlled functions make commissioning and support during operation easier. The current position of the valve is displayed via high visibility LEDs and fed back via electrical signals. The GEMÜ 1235 has been specially designed for valves with a stroke of 2.0 to 74.4 mm. 14 / 15
